HOPPERHCOCK FOR WATER=CLOSETS.

SPECIFICATION forming part of Letters Patent No. 388,896, dated September 4, 1888.

Application filed October 5, 1885. Serial No. 179,069. (No model.)

To [tZ whom it may concern:

Beitkuown that I, THOMAS W. MCFADDEN, a citizen ot' the United States, residing at Musl kegou, in the county of Muskegon and State of Michigan, have invented certain new and uselul Improvement-s in Hopper-Gocks for lVatenClosets, and I do declare the following to he a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the saine, reference beiug had to the accompanying drawings, and to the letters and iigures oi' reference marked thereon, which i'orm apart of this specilication.

This invention relates to au improvement in that class oi' inventions known as hoppercocks7 l'or water-closets, the object being to simplify the construction ol' the same, to in crease the durability ofthe valves by causing them to have perpendicular contact with their seats, and to provide a trap which shall effectnally prevent all escape of sewer-gas.

rlherefore, in order to fulfill these objects, my invention consists in constructing the body or main stem ot' the cock in three pieces, so that either one may be readily and easily duplicated.

It consists, also, in connecting the valves and lever attachment with one solid metallic stem and in the peculiar relative location of the waste and discharge pipes,whereby the emission ol sewer-gas is obstructed, and in the placing of the entire device directly below the seat oi' the water-closet in a perpendicular position, thereby rendering its action automatic and dispensing with all pulley and cable connections; and the invention further consists in certain peculiarities of construction, as will be hereinafter specifically set forth and claimed.

In the annexed drawings, illustrating my invention, Figure l is a vertical section through the device. Fig. 2 is a vertical end elevation, and Fig. 3 is a top plan View of the same.

Like letters ci' reference are used to designate like parts in the several views.

The main body of the cock consists, essentially, of the parts A B C.

A represents the central portion of this main body, and is made of any suitable metal, brass, perhaps, being preferred. This portion A is provided on each end with a suitableseat for the reception of the valves. it is also provided on one side, at or near the center, with an opening, a, into which passes the discharge coming from the closet proper through thc discharge-pipe.

B represents the lower portion of the cock, y which is provided with au opening, b,througlrwhich water is supplied to the cock through the watersupply pipe, and the part B is also provided with a horizontal bottom iiauge, D, of suitable proportions to enable the cock to be located lirmlyin its perpendicular position.

O represents the upper port-ion ofthe device or cock, and it is provided with an opening,c, which opens into the wastclpipe which carries away the waste from the closet. Thus the main body ol the cock is formed of three parts, situated one above the other, the lower 7o one having the watersupply opening, the middle one having the discharge-opening, andthe upper one having the wasteopeniug. The supply, discharge, and waste openings are all provided with outside threaded connections for the purpose of attaching the pipes thereto.

The upper end of the part O is provided with a suitable cap, E, which is of such a diameter as to allow the valvestem, with the upper valve attached, to be taken out when 8o required withoutdisturbiug the valve. Into the cap E is screwed the stu'ihngbox c. This stufiiugbox is for the purpose of packing the stem, and also of acting as a guide lor the same. The main body of the cock, as well as the cap and stuiiing-box, are all provided with inside and outside threaded connections for the purpose of fastening the whole device together. To the upper portion of the section O there is attached or cast solid therewith an arm or 9o standard, F, the upper end of which is conveniently formed with jaws, between which a lever, I, can rest and be i'ulcrunied therein upon a pivot.

G represents a solid metallic valve-stem, upon which at suitable distances apart are arranged the collars gland the valves H. There are two of these valves H, an upper and a lower one, and they are so arranged upon the stern Gr at such a distance apart that when roo either of them is closed upon its seat the other is sufficiently free from its seat to allow proper 25 therein.

space for the passage of water. These valves are secured in their places by means of screws and nuts provided on the stem for that purpose. 'Io the top of the stem is securely fast- 5 cned by suitable means, as a screw, a doublejawed joint, 71 to which is connected one end of the lever I.

j represents a connecting-rod by which motion is communicated from the seat of the Io closet to the valves H. This rod is also prefbut it is evident that this particular method ofconnecting the levers may be departed from, and any suitable joints may be employed for connecting the weighted lever I and the seatleverj with the stem which carries the valves.

zo The lever I is pivoted between the jaws of the standard F by a pivot, f. At one end it is connected with the joint h, preferably in the `manner shown in Fig. 2, by passing between the jaws of the said joint and being pivoted The other end of this lever is provided with a weight, O, which is movable upon the lever and can be adjusted thereon to a greater or less distance from the stem G, .so as to balance seats of variable sizes and weights.

3c It is secured in any desired position by a setscrew, and it may be provided with a small perforated lug or eye, o, for the attach ment of a cable or wire to enable the device to be operated at a distance when this method of operating is preferred.

In the drawings, Fig. LN represents the seat of a closet, and Ma portion of the frame ofthe same. To this latter portion M is attached a guide, 7c, for keeping the leverj in an upright The operation of the hopper cock the movable seat N is depressed and comes into contact with the lever j, which in turn depresses the stem G, to which the valves H are rIhis operation of the valves closes the waste and opens the supply passage. It will be noted that this lower valve, H,is opened against the pressure of the water within the supply-pipe, and also that the weight attached 5o to the lever I is raised in consequence of the will reverse the movement of the stem and its valves and close the supply and open the waste passage. Vhen the valves are in this position, it will be evident that the middle body or section of the cock will always contain a quantity 6c of water on account of the differencein height between the supply and waste pipes. Thus when the closet is not in use,this Water will fill the cock in such a manner as toform aperfect preventative against the return of sewer-gas from the waste.

Valves of my particular form are probably not new, and I do not, therefore, lay claim to theni,broadly. The construction and arrange ment, however, of these valves on asolid stem placed perpendicularly below the closet-seat and operated directly by the movement of the seat is an improvement. Another point of merit in this arrangement lies in the relative position ofthe discharge and waste-water pipes, which creates an eifectual sewer-gas trap when the closet is not in use; also,in consequence of the direct action of the device thesupplyyalve is closed by the pressure instead of against it, thus constituting a perfect and reliable watertightjoint, and consequently avoiding leakage.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. Ina hopper-cock for waterclosets, a solid stern carrying valves so situated thereon with reference to each other as that but one of them shall close upon its seat at a time, in combination with a perpendicular chamber constructed of three sections located one above the other, the lower one being provided with an opening for the entrance ofthe supply-pipe,the middle one being provided with an opening for the entrance of the discharge-pipe, andthe upper one being provided with an opening for the entrance of the waste-pipe, the said valve-carrying stem being actuated by contact with the seat itself and by a weighted lever whose extremity is attached to the said stem, substantially as and for the purposes shown and described.

2. The combination of the perpendicular chamber A, having opening a, section B, having opening b, and section C, having opening c. the valve-stem G,carrying valves H H,secured thereon by means of collars g, the standard F, the lever I, provided with weight O and fulcrumed atfin the standard and pivoted within the double-j awed joint h,attached to the upper extremity of the valve-stem, and the connecting-rod j, secured at one end. to the joint h, the other end connecting with the seat,all arranged and operating substantially as shown and described.

In testimony whereof I aflix my signature in presence of two witnesses.

THOMAS \V. MCFADDEN.
